The Pack plays no matter how frozen its fans get, because the field has a defroster and because the smart fans slip on the Kamik Greenbay 4 Boot before they step out of their farmhouse. This boot's removable 8mm Thermal Guard felt liner really comes in handy if it's a night game, because it keeps your foot's warmth circulating down to -40 degrees Fahrenheit. Hopefully they've got the win clenched by that point.
